To Use the Measurement Control Keys
The following procedure demonstrates how these keys function.
1
Connect power source to Counter, and turn on Counter.
All segments of the front-panel display will light up while the Counter
performs its power-on self-test, and then dashes are displayed.
The Counter is now ready to measure frequency of a signal applied to
CHANNEL 1 input. Note that the Freq and Ch1 annunciators light.
2
Connect an input signal to CHANNEL 1.
The Counter automatically displays the measured frequency of the input
signal. Note that the Run key indicator is ON.

Press Stop/Single key.
The Counter is put into Single mode and the current measurement is
completed. One measurement is taken with each press of Stop/Single key.
Note that the Stop/Single key indicator is ON.
4
Press Run key.
The Counter aborts any measurement in progress, and starts making
repetitive measurements. That is, the Counter is in a continuous
measurement loop.
5
Press Stop/Single key.
The Counter is put into Single mode.
6
Press Stats key until
ON SINGLE
menu item appears, then press any one
of the arrow keys to set
ON SINGLE
menu item to
N
.
The Counter is set to take N measurements on each Stop/Single keypress.
The state of
ON SINGLE
menu item affects the Stop/Single key operation
while statistics are enabled.
Observe that the Stats indicator is ON. This indicates statistical
processing is enabled.
